Hi, could someone help me with the example of my configuration below?

I have
*Client* <---> * Wireless Controller*: MYWLAN(802.1x EAP) <--->
*Freeradius.*
AAA Server setting in Controller with IP: 192.168.100.3 (my internal
freeradius)

Freeradius *Version 3.0.16 with Mysql*

*Two Freeradius servers: one HCRPP(internal) and CR(External)*
radcheck attribute is *NT-Password* (HCRPP) , and the user stored in the
database is without suffix.
*radcheck attribute is Cleartext-Password to (CR)*

*Freeradius HCRRP use EAP 802.1x and CR - PAP cleartext*

*What I need is  when a user authenticates without suffix or with suffix
(@hcrpp.com <http://hcrpp.com>), use EAP-PEAP or TLS to authenticates in my
local freeradius and if the suffix was @cr.net <http://cr.net> proxy
to 126.100.20.3 with cleartext password.*

When i'm logging with username and password *without suffix*, *it's works*,
but when i'm logging with *suffix *like testuser at hcrpp.com or testuser@
cr.net  i get this error message:

 suffix: Checking for suffix after "@"
